avenir write a patch to nesDS, what's new? He said... QUOTE
Extended the reset to "If not loaded from hbmenu/xenofile, returns DSi/3DS menu on DSi/3DS". stringsort() is now a wrapper for qsort(). extlink now accepts multibyte filename thanks to Unicode support. Directory listing is shown the same way as WinNT(8.3 lower case). <- If you name a file all lower case in 8.3... /nesDS.ini is used for configuration(minIni).
Add the shout-cuts for configuration.
Sound fixed.. better than 0.44b. Almost no noise(not the noise channel).
Sprite0y of 'per-scanline' fixed.
h-blank interrupt handler added, which was removed since 0.44b.
